CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The United States FAA has issued AD 2006-15-05 affecting Boeing 737 model aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/291, which will become effective on 31 August 2006.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, provides the legislative framework for ensuring the safety and efficiency of civil aviation in Australia. The Act enables the creation of regulations that serve the interests of air navigation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further specify the conditions under which ADs can be issued for types of aircraft or aeronautical products, with these directives being legislative instruments as per the Legislative Instruments Act 2003. These directives are integral to the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation, particularly Annex 8, which places the responsibility for airworthiness on the State of Design and the State of Registry. CASA, as Australia's national airworthiness authority, is mandated to issue ADs in response to those issued by the relevant State of Design, thereby ensuring compliance with international obligations and maintaining safety standards in the Australian aviation sector.
Scope and Application
The Civil Aviation Act 1988, through the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under this framework, CASA is empowered to issue ADs for specific types of aircraft or aeronautical products, aligning with the overarching goal of ensuring the safety of air navigation. These ADs are legislative instruments, subject to disallowance and the requirements of the Legislative Instruments Act 2003. The regulations extend their application to any aircraft registered in Australia, necessitating adherence to continuing airworthiness directives issued by CASA. The ADs are particularly significant as they are often issued in response to directives from the State of Design, ensuring compliance with international obligations under the Convention on International Civil Aviation. This process involves CASA evaluating directives from the design state, such as the United States Federal Aviation Administration’s AD 2006-15-05 for Boeing 737 model aircraft, and issuing corresponding Australian ADs as necessary. This approach underscores the collaborative nature of international aviation safety and the responsibility of the State of Registry to enforce these directives within their jurisdiction.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of civil aviation in Australia. Section 98 of the Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This regulatory power is exercised in accordance with international standards, such as those set out in Annex 8 to the Convention on International Civil Aviation, which allocates responsibility for the continuing airworthiness of aircraft types to the State of Design and the State of Registry.
Under these provisions, CASA must assess and, if necessary, issue ADs when the State of Design issues them for aircraft types registered in Australia. For example, the United States Federal Aviation Administration (FAA) issued AD 2006-15-05 for Boeing 737 models. As the United States is the State of Design for these aircraft, CASA assessed the directive and issued Australian AD/B737/291, effective from 31 August 2006. This process ensures that Australian aircraft meet international safety standards and comply with the continuing airworthiness requirements stipulated by the State of Design.
The obligations imposed by these regulations extend to ensuring that all relevant parties, including aircraft operators and manufacturers, comply with the ADs issued by CASA. Aircraft operators must adhere to the requirements set out in the ADs to maintain the airworthiness of their aircraft. Failure to comply with an AD can result in serious safety implications and potential legal consequences. CASA, as the national airworthiness authority, has the responsibility to enforce compliance and take necessary actions to ensure the safety of air navigation.
In terms of legal consequences, non-compliance with an AD can result in severe penalties. The specific penalties are not detailed within the provided text but generally, breaches of civil aviation regulations can lead to fines, enforcement actions, and potentially the grounding of non-compliant aircraft. The severity of the penalties often reflects the potential risk posed by the non-compliance to the safety of air navigation. Additionally, ongoing non-compliance may result in further enforcement measures, including legal proceedings and sanctions against the responsible parties.
